About FindSaunaPlunge
An independent directory of cold plunge, sauna, and contrast therapy studios across the United States.
Contrast therapy went from a niche athletic practice to something you can book in most American cities in about five years. The directories did not keep up. Search for a cold plunge near you and you get map listings with no temperature, no price, and no way to tell whether the place still exists.
This site exists to fix the specific things that make those listings useless. Every studio record carries the water temperature, the sauna type, the drop-in price, whether you get a private room, and — the part nobody else publishes — the date a person last confirmed all of it.
How it is built
Listings live in a version-controlled registry rather than a content management system. Every page, sitemap, and data feed on this site is generated from that registry at build time, which means a fact appears in exactly one place and cannot go stale in one view while staying current in another. If the registry does not contain something, the site does not display it.
The whole site is static HTML served from the edge. There is no tracking beyond aggregate analytics, no login, no newsletter wall, and no interstitials.
How it pays for itself
Studios can pay to be featured, which affects where they sit in a list and adds a badge. It does not change any fact on the page, and featured placement is always visibly labelled. We also earn commission on some equipment links, which are marked as sponsored. Editorial details — temperatures, prices, verification dates — are never for sale. That distinction is the entire value of the site; selling it would destroy the thing people come here for.
Machine-readable by design
A growing share of people find places by asking an AI assistant rather than by searching. That works only if the underlying data is structured and open, so we publish aversioned JSON feed of every live listing and anllms.txt describing the site. AI crawlers are explicitly allowed in our robots.txt. We would rather be cited accurately than gatekeep listings nobody can read.
Getting in touch
Corrections, additions, and studio submissions go tosubmit@findsaunaplunge.com, or through thelisting form. Corrections to an existing listing are handled before new submissions — if we have published something wrong about your studio, tell us and it gets fixed first.
